, p. 428 - 431 (2004)
A simple and environmentally friendly synthesis was developed for the preparation of 2-arylimidazoline derivatives and 2-arylbenzoxazole derivatives using a small pore size zeolite. The similar reaction was not applicable to the preparation of the sulfur-containing analogs cysteamine or 2-aminothiophenol, probably because of a disadvantageous reaction between the zeolite and the thio compound.

A synthetic method is presented for S?N bond formation starting from cheap and affordable materials. We show that (un)substituted N-protected cyclic eight-membered C2-symmetric sulfenamides have been prepared in a few steps using this procedure. The synthetic utility of these ambipolar derivatives was demonstrated in a variety of synthetic transformations affording different S,N-heterocyles of pharmaceutical relevance in one or two steps from simple starting materials. (Figure presented.).
THERMAL REARRANGEMENT OF O-THIOACYL DERIVATIVES OF N-ACYL-N-ARYLHYDROXYLAMINES
Drozd, V.N.
, p. 317 - 326 (2007/10/02)
The ability of the Ar-N-O-C=S system of atoms to undergo a thermal rearrangement of the Claisen type was investigated.On the basis of the experimental data it was concluded that the process is predominantly nonconcerted in nature.
